Before you commit to any property in Singapore, you should know exactly how much your monthly home loan repayments are likely to be, how they change when interest rates move, and whether they fit safely within your budget and regulatory limits.



A well-designed home loan calculator Singapore buyers can trust does three things: it estimates monthly repayments, checks affordability against rules like the Total Debt Servicing Ratio (TDSR), and lets you compare options across banks and loan types before you apply.



1. Why Estimating Monthly Repayments Comes Before Any Property Decision

For most Singapore buyers, the home loan is the largest financial commitment in their lives. Estimating repayments early helps you avoid over-stretching, missing out on approval, or having to downgrade later.



There are four key reasons to use a home loan repayment calculator before you even shortlist properties:



  • Affordability control: You see, in dollars, how much you can comfortably pay each month without breaching TDSR or your own budget.
  • Downpayment planning: You can work backwards from your desired monthly repayment to find a suitable loan amount and then the required cash/CPF downpayment.
  • Tenure optimisation: You can test different loan tenures (for example, 20 vs 25 vs 30 years) and see the trade-off between lower monthly repayment and higher total interest paid.
  • Bank comparison: You can simulate fixed and floating interest packages from banks such as DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB and others to see which structure suits you.


On Homejourney, you can start by estimating monthly repayments, then move directly into a guided request flow to compare suitable packages and request a callback for personalised advice via the same interface at Mortgage Rates .



2. Key Singapore Rules That Affect Your Home Loan Calculator Results

A calculator is only useful if it reflects Singapore’s actual housing rules. When you estimate monthly repayments, you should always consider how these three major frameworks affect the loan you can take:



2.1 Loan-to-Value (LTV) Limits

Loan-to-Value (LTV) is the maximum percentage of the property’s price or valuation that you can borrow. For HDB concessionary loans, the maximum LTV has been tightened over time, and from August 2024 the stated maximum LTV for eligible HDB loans is 75%, according to official and mainstream sources such as HDB and Ministry of National Development announcements. This means you must fund at least 25% of the purchase price or valuation (whichever is lower) using cash and/or CPF Ordinary Account (OA) savings.



For housing loans from financial institutions (for example, DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB and others), the maximum LTV for a first housing loan is also generally 75% under current rules, subject to conditions such as loan tenure and borrower’s age. These rules are set and periodically updated by the Monetary Authority of Singapore (MAS) and related agenciesMonetary Authority of Singapore .



When you use a mortgage calculator, always check whether it assumes a 75% LTV by default, or allows you to adjust the loan amount manually. This is important if you plan to borrow less than the maximum for safety.



2.2 Total Debt Servicing Ratio (TDSR)

The Total Debt Servicing Ratio caps the share of your gross monthly income that can go towards all debt obligations, including your housing loan, car loans, student loans, and credit card balances. MAS sets this TDSR cap at 55% for new housing loans, meaning your total monthly debt repayments should not exceed 55% of your gross monthly incomeMonetary Authority of Singapore .



A good home loan calculator will either show a TDSR indicator or let you key in your other monthly debts, so you can see if your estimated repayment would push you above this 55% cap. If it does, your loan amount will likely have to be reduced, or the tenure extended, subject to legal maximums.



2.3 Mortgage Servicing Ratio (MSR) for HDB and EC Buyers

For HDB flats and Executive Condominiums (ECs), the Mortgage Servicing Ratio (MSR) further limits what portion of your gross monthly income can go to housing loan repayments. MSR is currently capped at 30% of gross monthly income for loans to purchase HDB flats and ECs bought directly from developersHousing and Development Board Monetary Authority of Singapore .



This means that even if your TDSR is below 55%, your housing loan component cannot exceed 30% of your gross income for these property types. HDB buyers should ensure that any home loan repayment calculator has a clear MSR check; otherwise, estimates may overstate what you can actually borrow.



3. How a Home Loan Calculator Works: Core Inputs and Formula

Behind every mortgage calculator is a standard loan amortisation formula. You do not need to do the math yourself, but it is useful to understand what is happening in the background so you can adjust the inputs confidently.



3.1 Essential Inputs You Should Always Check

Any reliable home loan calculator in Singapore should ask for at least the following fields:



  • Property price or value: Usually the agreed purchase price or the property’s valuation, whichever is lower.
  • Loan amount: Often auto-calculated from LTV (for example, 75% of S$800,000 = S$600,000), but you should be able to override this.
  • Interest rate (per annum): For example, 3.0% p.a. for a fixed-rate package or a spread over SORA for floating packages.
  • Loan tenure: Number of years, typically up to 30 years for HDB and 35 years for private property, subject to age conditions and regulatory limitsMonetary Authority of Singapore .
  • Loan type: HDB loan vs bank loan; fixed rate vs floating rate; SORA-pegged vs board rate.
  • Buyer profile: Optional, but useful fields include citizenship, first-time buyer status, number of outstanding housing loans, and intended property type (HDB, condo, landed).


On Homejourney’s home loan calculator, these inputs feed into both a monthly repayment estimate and an eligibility check, which helps you understand not only the repayment amount but also whether banks are likely to approve that loan size at Mortgage Rates .



3.2 The Monthly Repayment Formula in Plain Language

The typical formula for monthly instalments on a fully amortising home loan is:



Monthly repayment = P × r × (1 + r)n / ((1 + r)n − 1)



Where:



  • P is the loan principal (for example, S$600,000).
  • r is the monthly interest rate (annual rate divided by 12).
  • n is the total number of monthly repayments (years × 12).


Over time, the interest portion of each instalment shrinks and the principal portion grows. A home loan repayment calculator does this amortisation automatically so you can see how much of your payment goes to interest versus principal in the early years versus later years.



3.3 Example: Estimating Repayments for a Typical Singapore Loan

Imagine you are buying a private condo valued at S$1,000,000 and taking a 75% bank loan (S$750,000) over 25 years at an effective interest rate of 3.2% p.a. The calculator converts 3.2% p.a. into a monthly rate and applies the formula to show your monthly repayment.



Because interest rates and bank packages change frequently, you should always verify the latest rates with banks or via a live comparison service like Homejourney’s multi-bank request flow, which pulls current packages from banks such as DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB, and others at Mortgage Rates . Exact figures should be checked against current offers and official disclosures.



4. Understanding SORA and Interest Rates in Your Home Loan Calculator

Most new floating-rate home loans in Singapore are pegged to SORA, the Singapore Overnight Rate Average. SORA is an interest rate benchmark published by MAS based on actual overnight interbank transactionsMonetary Authority of Singapore . Banks often price mortgages off compounded 1‑month, 3‑month, or 6‑month SORA, plus a fixed spread.



For example, a package might be quoted as “3‑month compounded SORA + 0.70% p.a.” for the first few years, then revert to a higher spread after the promotional period. Your home loan calculator should let you input either the all‑in rate (for example 3.1% p.a.) or the benchmark plus spread so you can test how changes in SORA may affect your estimated monthly repayments.



Recent data from independent dashboards tracking MAS statistics show that 3‑month compounded SORA has traded around the low–to–mid single digit range in 2026, with some modest fluctuations. Forecasts suggest SORA could drift slightly higher or stabilise depending on global interest rate movements and MAS policy decisions. Exact levels and forecasts should always be checked directly against current MAS data or reputable rate trackers.



The chart below shows recent interest rate trends in Singapore:





When using a property loan estimate, it is sensible to test both a base-case scenario and a stress-test scenario with slightly higher rates, to see how your monthly repayment would change if SORA rises.



5. Fixed vs Floating: How to Compare in a Mortgage Calculator

When you estimate monthly repayments, one of the biggest choices is between fixed-rate and floating-rate loans. A calculator helps you simulate both options, but you should understand their trade-offs.



5.1 Fixed-Rate Home Loans

A fixed-rate package keeps your interest rate (and therefore your monthly repayment) unchanged for a lock-in period, typically 2–5 years, depending on the bank. After the fixed period, the loan usually converts to a floating package, often pegged to SORA or a board rate.



Advantages:



  • Predictable monthly repayments during the lock-in period.
  • Easier to plan your budget, especially for first-time buyers.


Trade-offs:



  • Initial rate may be slightly higher than floating packages.
  • Prepayment or refinancing during lock-in may trigger penalties.


5.2 Floating-Rate (SORA-Pegged) Home Loans

Floating packages move with SORA, plus a fixed spread set by the bank. Your monthly repayment can rise or fall as SORA changes.



Advantages:



  • Often start with a lower rate than fixed packages in normal conditions.
  • Benefit if interest rates fall.


Trade-offs:



  • Repayment amounts are less predictable.
  • Higher stress if rates rise more than expected.


In a mortgage calculator, you can input different interest-rate assumptions to see how sensitive your monthly repayment is to rate changes. For example, test your base scenario (e.g. 3.0% p.a.) and a stress scenario (e.g. 3.5%–4.0% p.a.). If your budget is strained in the stress scenario, you may want to lower the loan amount or extend tenure, subject to MAS and HDB limitsMonetary Authority of Singapore Housing and Development Board .



6. Step-by-Step: How to Use a Home Loan Calculator in Singapore

The process of using a calculator should mirror the way banks assess your loan. Here is a step-by-step framework you can follow, using Homejourney’s home loan repayment calculator or a similar tool.



6.1 Step 1 – Decide Your Target Monthly Budget

Before entering any property price, start with your preferred monthly budget. Add up your current monthly expenses, including:



  • Existing loan repayments (car loans, student loans, personal loans).
  • Credit card instalments and minimum payments.
  • Insurance premiums and recurring household costs.


Then decide a comfortable monthly housing budget. Staying well below the 55% TDSR cap and 30% MSR cap (for HDB/EC) gives you a safety bufferMonetary Authority of Singapore Housing and Development Board . For example, some borrowers prefer to keep housing repayments at 25–35% of their gross income, depending on their lifestyle and dependants.



6.2 Step 2 – Enter Property Price and Downpayment

For an HDB flat, check the latest LTV limits and grants from official HDB sources and mainstream coverageHousing and Development Board . For a private property, refer to MAS and bank guidelinesMonetary Authority of Singapore . Then in the calculator:



  1. Enter the property price or valuation (for example, S$600,000 for an HDB resale flat, or S$1,200,000 for a condo).
  2. Enter your intended downpayment (cash + CPF). The calculator may auto-calculate the maximum loan based on LTV, but you can reduce the loan amount if you wish.
  3. Ensure your downpayment meets the minimum cash/CPF breakdown required under current rules.


6.3 Step 3 – Select Loan Type, Tenure, and Interest Rate

Next, choose between HDB loan (if eligible) and bank loan. Then:



  • Set your loan tenure (e.g. 20, 25, or 30 years). Note that longer tenures reduce monthly repayments but increase total interest costMonetary Authority of Singapore .
  • For bank loans, input an estimated interest rate (e.g. latest fixed or SORA-pegged rate). Use current published rates from banks or comparison tools, or the live bank rate range available via Homejourney at Mortgage Rates .
  • For HDB loans, use the latest HDB concessionary interest rate from official HDB sourcesHousing and Development Board .


The calculator will compute your initial monthly repayment estimate based on these inputs.



6.4 Step 4 – Add Income and Debt to Check TDSR and MSR

This is where a simple repayment calculator becomes a more powerful eligibility calculator. Enter:



  • Your gross monthly income (and, if applicable, your co-borrower’s income).
  • Your existing monthly debt obligations.


The calculator should then estimate your TDSR and, if you are buying an HDB or EC, your MSR. If the projected housing repayment causes you to exceed 55% TDSR or 30% MSR, you may need to:



  • Reduce the loan amount by increasing your downpayment;
  • Extend the loan tenure, subject to maximums; or
  • Consider a lower-priced property.


On Homejourney, this eligibility calculation is integrated into the home loan calculator so you can see at a glance whether your current scenario looks feasible at Mortgage Rates .



6.5 Step 5 – Compare Scenarios and Save the Safe Option

Once you have a baseline scenario, create a few additional scenarios:



  • Shorter tenure vs longer tenure (e.g. 20 vs 30 years).
  • HDB loan vs bank loan (for eligible buyers).
  • Base interest rate vs higher stress rate.


Note which scenario gives you a comfortable monthly repayment with a healthy buffer under TDSR/MSR. Save or screenshot that scenario; this becomes your reference when speaking to banks or brokers.



Homejourney lets you move directly from this stage into a multi-bank request flow, where you can submit one request and receive guidance on suitable packages from partners including DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB, and others at https://www.homejourney.sg/mortgage/home-loan-calculator#loan-request.



7. Process Overview: From Calculator Estimate to Bank Approval

Using a home loan calculator is the first step in a larger journey that goes from planning to approval and, eventually, disbursement. Below is an end-to-end overview for a typical buyer in Singapore.



7.1 Typical Timeline and Milestones

While exact timelines vary by bank and case complexity, a common process for a home purchase looks like this:



  1. Pre-planning (1–2 weeks): Use a mortgage calculator to estimate repayments and determine a realistic budget.
  2. In-principle approval (IPA) (1–2 weeks): Submit income documents to one or more banks or via Homejourney’s multi-bank request flow to obtain conditional approval for a specific loan amount.
  3. Property search and offer (varies): Shortlist properties and, once ready, exercise an Option to Purchase (OTP) or book a flat.
  4. Formal loan approval (1–3 weeks): Provide the specific property details and complete bank’s underwriting. For HDB loans, submit the HDB Loan Eligibility (HLE) or equivalent application via official HDB systemsHousing and Development Board .
  5. Legal and completion (8–12 weeks for resale): Lawyers complete conveyancing and loan documents; bank disburses funds on completion.


At each stage, having clear repayment estimates makes it easier to make decisions quickly and safely.



7.2 Where Homejourney Fits in the Journey

Homejourney is designed to make this journey safer and more convenient by:



  • Providing a home loan calculator that estimates monthly repayments and checks basic eligibility in one flow at Mortgage Rates .
  • Allowing you to submit one request for guidance across multiple banks such as DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB and others, instead of approaching each bank separately.
  • Connecting you with Homejourney Mortgage Brokers who can help explain trade-offs between fixed and floating packages and highlight lock-in conditions and penalties.
  • Linking you to Property Search so you can filter for properties that fit within the safe repayment range you have already tested.


8. Documentation Checklist for Home Loan Applications

Once your calculator shows a comfortable scenario, the next step is preparing documents. Different banks may request slightly different items, but most will ask for the following:



8.1 Income and Employment Documents

  • Latest 3 months’ computerised payslips (for salaried employees).
  • Latest 6–12 months’ commission statements, if applicable.
  • Latest Notice of Assessment from IRAS (tax assessment).
  • CPF contribution history (usually 12 months) from the CPF websiteCentral Provident Fund Board .
  • Employment letter (for new hires or overseas income, where requested).


8.2 Self-Employed or Variable-Income Documents

  • Last 2 years’ IRAS Notices of Assessment.
  • Business financial statements (where applicable).
  • Bank statements to substantiate cash flows (number of months may vary by bank).


8.3 Property-Related Documents

  • Option to Purchase (OTP) for resale or developer’s booking form for new launches.
  • HDB flat particulars or private property address and details.
  • Any existing loan statements if you are refinancing.


8.4 Identification and Supporting Documents

  • NRIC or passport.
  • Proof of address, if requested.
  • Marriage certificate or proof of relationship for joint applications (where relevant for HDB or grants).Housing and Development Board


Homejourney’s loan request flow can help you organise these documents in advance, so you can upload or share them efficiently when banks or brokers request them.



9. Pro Tips: Using a Home Loan Calculator Like a Professional

Mortgage specialists and analysts often use calculators in a more advanced way to stress-test scenarios and avoid surprises. You can borrow some of these techniques to improve your own decision-making.



9.1 Always Run a Rate Shock Scenario

Instead of calculating your monthly repayment at only one interest rate, try at least two or three:



  • Current estimated rate (for example, latest fixed or SORA-pegged rate).
  • Moderately higher rate (for example, +0.5 percentage points).
  • Stress scenario (for example, +1.0 percentage point).


If the stress scenario repayment would push your housing costs beyond your comfort level or close to TDSR/MSR caps, consider reducing your loan size or leaving more buffer in your monthly budget.



9.2 Test Different Tenures Strategically

Use the calculator to see how monthly repayment and total interest change as you vary the tenure. Often, a modest increase in monthly repayment can significantly reduce total interest across 20–30 years.



A disciplined strategy some borrowers adopt is to choose a safer, longer tenure for approval purposes, but then voluntarily pay more each month when finances allow. This approach should only be used after confirming your bank’s prepayment rules and charges.



9.3 Factor In Non-Loan Property Costs

A home loan repayment calculator shows only the mortgage itself. You should separately set aside amounts for:



  • Property tax and fire insurance.
  • Condo maintenance fees or HDB service and conservancy charges.
  • Renovation costs and ongoing maintenance (for example, aircon servicing, which you can manage with reliable providers at Aircon Services ).


Including these in your budget will give you a more realistic picture of affordability, even though they are not part of the loan instalment.



9.4 Align Your Property Search with Your Calculator Result

Once you know your safe price range and monthly repayment estimate, use Property Search to filter for listings within that range. This prevents the common mistake of falling in love with a property that will strain your finances and potentially fail to meet TDSR/MSR requirements.



10. Refinancing: Using a Home Loan Calculator to Decide If It Is Worth It

Existing property owners can also use a mortgage calculator to evaluate refinancing. The key questions are whether you will save on monthly repayments and whether those savings exceed any switching costs over a reasonable timeframe.



10.1 Key Inputs for a Refinancing Calculator

To estimate the impact of refinancing, you will need:



  • Outstanding loan amount and remaining tenure.
  • Current interest rate and monthly repayment.
  • Proposed new interest rate and tenure (from the refinancing bank).
  • Break costs, legal fees, valuation fees, and any subsidies.


Many refinancing calculators allow you to compare “current package vs proposed package” side-by-side. You can approximate this on Homejourney by entering your current package as one scenario and your proposed package as another at Mortgage Rates .



10.2 Deciding Whether to Refinance

Refinancing often makes sense when there is a material difference between your current rate and the best available new rate, and when your lock-in period has ended or penalties are modest. However, you should consider:



  • How long you plan to hold the property.
  • Whether the new package has its own lock-in period.
  • How total costs (including fees) compare over the next few years.


Homejourney’s multi-bank request flow is designed to simplify this decision by letting you submit one refinancing request and receive guidance on suitable packages from multiple banks quickly at https://www.homejourney.sg/mortgage/home-loan-calculator#loan-request.



11. Homejourney’s Home Loan Calculator and Multi-Bank Request Flow

Homejourney integrates its home loan calculator with a broader set of tools to help you move from simple estimates to a bank-ready decision.



11.1 Calculator Features Focused on Safety and Transparency

Homejourney’s mortgage calculator is built around three core goals: safety, transparency, and convenience. To support these, it is designed to:



  • Estimate monthly repayments clearly, broken down by loan type, tenure, and interest rate.
  • Check basic eligibility by aligning with rules such as LTV, TDSR, and MSR using current official frameworks from MAS and HDBMonetary Authority of Singapore Housing and Development Board .
  • Let you test scenarios such as higher interest rates, different tenures, and different loan amounts.
  • Connect you to guidance via a callback request if you want help comparing packages or understanding risk.


11.2 Multi-Bank Request and Callback

Instead of approaching banks one by one, you can use Homejourney’s loan request form at https://www.homejourney.sg/mortgage/home-loan-calculator#loan-request to:



  • Share your estimated loan needs and property details once.
  • Request guidance across major banks such as DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, CIMB, RHB, Public Bank, Hong Leong Bank, Citibank and more.
  • Connect with Homejourney Mortgage Brokers who can explain how each package interacts with SORA trends, lock-in periods, and your long-term plans.


This approach supports better decision-making while keeping all communication in one safe, auditable environment.



12. Common Pitfalls When Using a Home Loan Calculator

Even an accurate calculator can lead to poor decisions if used incorrectly. Here are common mistakes to avoid:



  • Ignoring future rate changes: Only testing today’s interest rate and not stress-testing a higher rate scenario.
  • Overestimating income: Using gross income without accounting for variable components that banks may discount.
  • Understating other debts: Forgetting car loans, education loans, and large credit card instalments, which affect TDSR.
  • Not checking official rules: Assuming old LTV or grant rules still apply instead of checking current MAS and HDB guidelinesMonetary Authority of Singapore Housing and Development Board .
  • Mixing CPF and cash planning: Focusing only on cash repayment and ignoring CPF OA usage limits and long-term retirement needsCentral Provident Fund Board .


Using Homejourney’s tools alongside official sources from MAS, HDB, and CPF helps reduce these risks and keep your planning aligned with current rules.



13. Important Disclaimers and When to Seek Professional Advice

All home loan calculator outputs are estimates based on the inputs you provide and simplified assumptions. Actual bank approvals will depend on full underwriting, including credit history, income proof, existing liabilities, property characteristics, and internal bank policies.



Regulations such as LTV limits, TDSR caps, MSR caps, and interest-rate benchmarks are subject to change by authorities such as MAS, HDB, and other government agencies. You should always verify critical numbers directly with official sources like MAS, HDB, and CPF before making binding commitmentsMonetary Authority of Singapore Housing and Development Board Central Provident Fund Board .



For complex situations—such as multiple properties, foreign income, variable commissions, or self-employment—it is advisable to consult qualified mortgage specialists or licensed financial advisers. Homejourney’s Mortgage Brokers can provide personalised guidance based on your profile when you request a callback from the calculator flow at https://www.homejourney.sg/mortgage/home-loan-calculator#loan-request.



14. Frequently Asked Questions (FAQ)

14.1 How accurate is a home loan calculator in Singapore?

A home loan calculator gives a good approximation of monthly repayments if you input realistic values for loan amount, tenure, and interest rate. However, final bank-approved figures may differ because banks apply their own stress-test rates, internal risk assessments, and detailed checks against TDSR, MSR, and LTV rulesMonetary Authority of Singapore Housing and Development Board . Treat calculator results as planning tools, not guarantees.



14.2 Can a calculator tell me exactly how much the bank will lend?

No calculator can guarantee an exact approval amount. It can estimate a safe range based on your stated income, debts, and public rules like TDSR and MSR, but only the bank’s full underwriting process can confirm the final loan quantum. For a more reliable indication, request an in-principle approval from one or more banks or use Homejourney’s multi-bank request flow at Mortgage Rates .



14.3 What interest rate should I key into the calculator?

You should use current indicative rates from reputable sources—such as published bank packages, Homejourney’s rate comparison, or official bank communications—and then also test a higher rate for safety. For SORA-pegged packages, refer to current SORA levels from MAS-linked sources or recognised rate dashboards, and remember to add the bank’s spreadMonetary Authority of Singapore .



14.4 How do I estimate HDB loan repayments vs bank loan repayments?

To compare, run two scenarios in the calculator: one using the latest HDB concessionary rate and HDB’s LTV/tenure limits, and another using a bank’s rate and LTV framework. Official HDB sources explain current concessionary loan conditions, including eligibility, LTV and interest-rate formula, which should be checked directlyHousing and Development Board . Then compare the resulting monthly repayments and total interest.



14.5 Does the calculator include Buyer’s Stamp Duty (BSD) or ABSD?

A standard home loan repayment calculator typically focuses on loan instalments and does not include Buyer’s Stamp Duty (BSD) or Additional Buyer’s Stamp Duty (ABSD). You may need a separate stamp duty calculator or to consult IRAS/official guidelines for these amounts. Always account for BSD and any applicable ABSD in your total cash/CPF planning.



14.6 Is CPF usage automatically reflected in the calculator?

Most calculators allow you to specify how much CPF OA you plan to use for downpayment and monthly repayments, but they may not automatically enforce CPF limits or retirement requirements. For CPF-related planning, check current rules directly with CPF Board and consider how much CPF you want to keep for retirement savingsCentral Provident Fund Board .



14.7 How can I use a calculator to see if refinancing is worth it?

Enter your current loan amount, remaining tenure, and interest rate as one scenario. Then enter the proposed new rate and tenure as another. Compare the difference in monthly repayment and total interest, and weigh this against any refinancing costs. If the net savings over the period you plan to keep the property are meaningful, refinancing may be worth exploring further.



14.8 What if I have irregular income or multiple sources of income?

For irregular or multi-source income (for example, commissions, freelance payments, overseas income), banks may apply haircuts or average your income over longer periods. A calculator can still help you test scenarios, but its assumptions may be too simple. In these cases, it is especially useful to request personalised guidance from mortgage specialists through Homejourney’s callback feature.



14.9 Can foreigners use the home loan calculator for Singapore properties?

Yes, foreigners can use the calculator to estimate repayments on Singapore properties. However, eligibility, LTV limits, ABSD rates, and available packages may differ for foreign buyers, so you should verify the applicable rules with MAS, IRAS, and the banks, and seek tailored advice.



14.10 What is the next step after I finish using the calculator?

After you have a comfortable repayment estimate and a target price range, you can:



  • Use Property Search to find properties that match your budget.
  • Submit a loan request via Homejourney’s calculator flow to compare suitable packages and request a callback at https://www.homejourney.sg/mortgage/home-loan-calculator#loan-request.
  • Gather your documents using the checklist above, so you are ready when banks or brokers request them.


Planning your Singapore home loan should start with a clear, realistic estimate of your monthly repayments using a reliable calculator, then progress to eligibility checks, bank comparisons, and professional guidance where needed. By combining Homejourney’s tools with official information from MAS, HDB, and CPF, you can make confident, well-informed decisions about your property financing in a safe and transparent way.
